I am asking this questions due to the teachings, beliefs and practices of different religions.
In short, yes. There are degrees of truths in many religions. Personally I think that looking for "a true religion" is the wrong approach to healthy spirituality.
It is sad that many controlling groups use half truths and pseudo facts to entice people to join them. On the other hand, some well intended religious organizations may try to force people to do believe things that are not accurate or true.
Also, please keep in mind that knowledge of some truthful facts are not the only things that people look for when joining a religion. Some people can't care less if they are believing or saying something that doesn't make sense. Instead, they care more of what religions make them feel. Their feeling part of a community, feeling taken care of, feeling hope, staying away from the streets, etc, those things are more important to them than if what they preach is accurate.
